Methods 656 cases of superficial vein puncture in adults randomly divided into observation group and control group. The observation group took 30-40 needle at the top of the puncture vein, then returned to the 1-2mm after the blood was returned, then the steel needle retreated 1-2mm, and finally the whole indwelling needle was sent into the blood vessel to draw out the needle and fixed with 3M. On the basis of the original needle point, then back 0, 5cm puncture increased the length of the needle while puncturing, and the control group received routine puncture.

The observation group was obviously superior to the control group (P, 0.05). Conclusion the puncture time increased The length of the needle helps to reduce the occurrence of the missing needle.
